SPECIFICATION forming part of Letters Patent No. 382.610, dated May 8, 18E 8.

\ Application tiled April 20, 1887. Serial No. 235,5l5. (No model.) A

To all whom t may concern:

Be it knownthat I, JOSEPH ELLIooTT i HoLMEs, a citizen of the United States, resid- Transferring vGases or Liquids Under Pressure;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in appliances or apparatus for transporting and transferring gases, especially when under pressure or in a liquidl form. y

The objects of my invention are, irst, t overcome a difliculty which has long been had in transferring gases from one holder to another withoutv a reduction of pressure corresponding to the additional amount of area or volume of the holder to be lilled, or to maintain the same pressure after the transfer as that in i the original holder, and to increase the pressure, if desired; second, to form a gasholder of suflicient capacity to contain and transfer any desired quantity of compressed gas or liquefied gas from the manufactory to any point where gas under pressure isrequired, such as com"-l bined refrigerating-safes where the fixed gasholders are to be supplied with compressed or liquefied ammoniacal gas, and to ships and torpedo-boats when carbonio-acid gas is employed as a motive force for submarine navi-- gation, or apparatus for aerating beverages, and for extinguishing tires. I attain these objects by introducinginto the gas-holder (which may be of the usual form to contain gases under pressure) an elasticilexible diaphragm, preferably formed of rubber, and of half of the length of the gas-holder, the body or cylindrical portion of which is made sufciently thin to'be thoroughly iiexible, one end being closed by a head of suflicient thickness to be self-supporting and to conform to the shape of the end of the gasholder. Upon the other end of this diaphragm is formed a iiange turn-A ing outward, -extending 'into and forming a gasket for a Iianged joint connecting the two halves of the holder. This diaphragm consti- Vtutes a division between the two heads of the holder, separating any substances that may be contained therein, and by its flexibility can be transferred from' one end to the other by the introduction of any gaseous or liquid substance introduced into either end of the holder,- causing a displacement or transfer of whatever substance may be contained in the oppo:k site end. rlhus for `the transportation and transfer of gas (the diaphragm being forced to the end to be filled to 'displace all air or other matter) the holder is iilled in the ordinary manner by the use of force-pumps or other devices at the manufactory and conveyed to different points where compressed gas is required and connection formed between the receptacle or holder containing the gas and one to be iilled. The reduced pressure caused vby the discharge is restored to the original amount stood, reference is had to the accompanying drawings, in which Figure 1 represents a gas holder or receptacle, partly in section, made in conformity with my invent-ion, showing lits lgeneral construction. cross-section at A A, Fig. l, ofthe holder.

B B indicates the shell, cylindrical in form, which is made in two equal sections and provided With strong flanges O, by which the two sections are secured or bolted together; D, the heads, which are made convex outward and securely attached to and closing the ends of the cylinder. In these heads at each end of the holder are arranged valves E, for charging and discharging, which are protected from .injury by guards G Gr, which 'are secured on projections H, formed on the heads. Y

I is a chamber formed in the projectionsH, which are open to the valves E and communicate with the interior of the holder by means of small holes or perforations K, the combined area. of which is not less than one and one- Fig. 2 is an end view, and Fig. 3 is a half time the area of the passage through the IOO L L indicate the fiexible hollow diaphragm, (shown distended and filled with fluid or liquid,) and M the diaphragm (shown in broken lines) when the holder is in the process of being charged or discharged of its contents.

N indicates the re-enforcing or strengthenving of the end of the diaphragm by introducing strong canvas or wire-cloth to prevent its being pressed into the perforations K in the heads of the holder and being injured thereby.

O is aflange formed on the open end ofthe diaphragm, which forms a gasket in the joint between the sections of the cylindrical holder and the medium of connection between the diaphragm and the holder.

I am aware that prior to my invention dexible hollow daphragms have been used in connection with holders of various kinds for different purposeswsuch as the discharge of gas with a uniform pressure for illumination, also forthe administration of gases in dental or surgical operations, but with slight pressurewhich I do not broadly claim; but

What I do claim as new and useful and my invention is rIhe sectional cylindrical holder B for liqueed ammoniacal gas orother like uids under pressure, consisting of two sections each having a flanged portion, C, with means for fastening the sections together, and heads D, which are provided with inlet and outlet pipes with valves E, chamber I, and perforated passage K, in combination with the exible elastic diaphragm L, having a reenforcement, N, arranged in said holder, substantial] y as and for the purposes set forth.

In testimony whereof I aiix my signature in presence of two witnesses.
